METHOD OF LASER BEAM GUIDANCE TO OBJECT Russian patent published in 2024 - IPC G02B26/08 H01S3/10 

FIELD: optical-mechanical instrument making.

SUBSTANCE: invention relates to optical-mechanical instrument making, to aiming a laser beam at objects. Method of laser beam guidance to object includes preliminary guidance of laser beam according to target designation data by coarse channel and processing of error of coarse channel by accurate channel according to measurements of coordinates of observed object by television receiving device, optical axis of which is aligned with optical axis of laser, and 4-quadrant photodetector, optically interfaced with output telescope of guidance system. Signal measured at the output of the television receiving device is fed to the input of the low-pass filter with a cutoff frequency, from the output of the low-pass filter, the signal is fed to the input of the accurate channel, using this signal, directing a laser beam to the object, measuring the coordinate of the laser radiation reflected from object by 4-quadrant photodetector, from output of 4-quadrant photodetector, the signal is transmitted to the input of the high-pass filter with a cutoff frequency ω_cut, equal to low-pass filter cutoff frequency, and is supplied to the input of the accurate channel in total with the signal from the output of the low-pass filter.

EFFECT: higher accuracy of guidance.
